Alignment Questions
Getting to Know the Team and Timeline
- Who from your organization will be directly involved in selecting and approving the subsea production system (names and roles)?
- Which of these roles best describes the primary sponsor for the procurement decision?
- What is the target first‑oil date we should be designing the delivery schedule around?
- Please enter the specific date or range for the first‑oil target (if known).
- How confident is the core team that the current project timeline will hold through installation?
- Who is the single point of contact we should escalate schedule or technical clarifications to?
Are We All Using the Same Definition of 'On‑Time'?
- Which stakeholder in your group would most strongly disagree with your current definition of ‘on‑time, low‑risk delivery’ and why might they disagree?
- For each stakeholder listed, what does ‘on‑time delivery’ mean in practical terms (e.g., delivery to yard, FAT complete, onsite ready for loadout)?
- How does each key stakeholder define 'low‑risk'—is it schedule certainty, minimal interventions, warranty terms, or something else? Please map stakeholders to their top priority.
- Are there any non‑negotiable contractual or regulatory milestones that must be met to satisfy a stakeholder’s definition of ‘on‑time’?
- If stakeholders’ definitions conflict, which group's definition typically takes precedence and why?
Invisible Deadlines: The Approvals That Kill Schedules
- Which hidden or informal approvals have historically derailed your project timelines (e.g., third‑party certifier, host engineering sign‑off, finance gates)?
- How long do each of those approvals typically take from submission to sign‑off in your experience?
- Which internal governance gates (e.g., FEED approval, PCI, gate reviews) are scheduled before contract award and what are their dates?
- Is there a single approval or external dependency that, if delayed two weeks, would force the installation campaign to slip a season?
- If yes, please name that dependency and describe why a two‑week slip is critical.
Weather Windows and the Cost of a Missed Season
- Imagine the installation weather window moves by a season — who on your team would bear the biggest political or financial pain, and how would they describe it?
- What are your preferred and absolute‑latest installation windows (months/seasons), and how flexible are they?

Who Owns the Interfaces — And Where Do They Break?
- Pick one interface you expect to be the most contentious (supplier↔SURF contractor, SURF↔host, supplier↔host) and tell us why it worries you.
- For the following interfaces, who currently owns design responsibility and who owns installation responsibility? (Select all that apply.)
- Do you have a current RACI or interface matrix we can review, and when was it last updated?
- How have interface disagreements been resolved in past projects—formal change control, executive escalation, or informal compromise?
- Are there technical interfaces (electrical, control, mechanical) where you require our vendor to absorb responsibility rather than share it? Please specify which and why.
What Trade‑Offs Would You Make to Protect the Schedule?
- If you had to choose today: accept a small schedule acceleration with higher technical risk, or protect technical margins and accept a longer manufacturing lead time—what would you pick and why?

- Please list the long‑lead items you consider critical and their current lead times.
- Are alternative or dual‑source suppliers prequalified for any of those long‑lead items?

Where projects like this usually fail — tell me your story
- When you look back at comparable subsea projects, what single failure mode would you say caused the largest cost/time impact?
- Which long‑lead components keep you awake at night (select all that apply)?
- Give a concrete example of a vendor performance issue you’ve faced (what happened, timeline impact, how it was resolved).
- Where do your integration points with SURF and the host FPU create the most uncertainty (mechanical interfaces, control logic, schedule handoffs, testing)?
- Describe a near‑miss or close call on a past project—what early signals were missed and what would you want to capture earlier next time?
- How do previous supplier warranties, workmanship records, or reference projects influence your current vendor risk tolerance?
If time slips, how bad does it get?
- If the subsea equipment delivery shifts beyond your weather‑window by one month, does that delay mean a few extra days or a full year of cost and schedule escalation?
- What is your absolute last acceptable installation season (month/year) before first‑oil is compromised?
- How do you currently quantify the cost of a slipped installation campaign (vessel day‑rate exposure, deferred production loss, contractual penalties)?
- What contingency triggers do you want explicitly defined (e.g., X‑week manufacturing delay triggers alternative procurement or chartering of a standby vessel)?
- Have you modelled compressed commissioning (shortened FAT, parallel testing) as an acceptable mitigation—what margin of schedule compression is tolerable?
What would 25 years of trouble‑free production actually look like to you?
- What specific reliability metrics matter most: MTTF, probability of intervention over 25 years, allowable leak rate, or something else?
- How do you define an acceptable intervention risk (e.g., 1 intervention per 25 years, per system, per cluster)?
- Which success signals will you use to sign off the subsea system at commissioning (first‑oil achieved, performance vs acceptance curves, demonstrable reliability tests)?
- What hard constraints on capex or schedule are non‑negotiable, and where are you willing to trade cost for schedule or vice versa?
- How emotionally costly would an unplanned intervention be for your team—what reputational or career exposure do you consider?
Do you trust the maker to own the timeline?
- When a vendor promises vertical integration will guarantee schedule, what would make you skeptical rather than reassured?
- Rate your current confidence in supplier manufacturing delivery on comparable projects.
- Which manufacturing milestones are on your critical path and must be visible weekly (e.g., forging completion, machining start, assembly start, HIL test window)?
- What evidence would you need to prove the supplier’s manufacturing control—sample KPIs, factory tour, third‑party audit, or test data?
- Are there supply‑chain single points of failure you’re most worried about (specialty vendors, single source forgings, proprietary electronics)? Please list and indicate lead times.
What would make you pause before we loaded out?
- What minimum set of tests and signoffs do you require before authorizing shipment to the installation site?
- Who has authority to sign final acceptance for shipment and what documentation do they require?

- What spare parts and critical consumables do you insist are shipped with the first delivery, and who inventories them on receipt?
If the schedule breaks, who does what and when?
- What remedies do you expect for supplier‑caused delivery delays (liquidated damages, accelerated deliveries, replacement equipment, performance bonds)?
- Describe your preferred governance cadence for resolving schedule or design changes (weekly program reviews, executive steering, joint change board).

- How do you expect post‑installation support to be structured (on‑call OEM teams, spares pool, guaranteed MTTR targets)?
If you could lock three non‑negotiables into the contract, what would they be?
- Please list and rank up to five non‑negotiable items (e.g., absolute delivery month, defined intervention risk, acceptance criteria, penalty structure).
- Which of these are tradeable if we offered more schedule certainty, and which are absolute red lines?
- How often would you like a shared program dashboard updated and who needs access (project team, exec sponsor, SURF contractor)?
- Would a dedicated shared channel for issues and continuous improvement (e.g., joint Slack/Teams channel) help your governance and fast decision making?
- Realistically, how soon should we schedule a joint workshop to translate these non‑negotiables into practical milestones and acceptance tests?
