Existing service

Gemini has worked under the HESS / Chevron charter through Marine Creation.

Proposed 2027 scope

Crew change, field supply and agreed offtake / bunkering duties, subject to upgrades and acceptance.

Bunkering concerns

FOS Gemini · hose handling and dry-break couplings

1 · Hose handling

The vessel has no dedicated securing point and suggested a shark jaw.

The handling arrangement and communications need agreement.

Proposed hose watch and bridge reportingManagement proposes an untied hose, continuous monitoring by the duty officer or AB, and reporting hose movement to the bridge. For review, not an approved operating procedure.Hose free to moveDuty officer / ABContinuous deck watchReport movementBridgeManagement proposal: hose untied; brief the vessel.

2 · Dry-break couplings

Only FO currently has a dry-break coupling. Compatible FW / FO connections are required.

Existing and planned dry-break connectionsOnly fuel oil is currently fitted with a dry-break coupling. Required compatible fresh-water and fuel-oil TODO connections are to be fitted during dry dock before return to hire. Dashed outlines indicate planned work.Reported 13 SeptemberDry-dock planFODry break fittedCompatible FW / FO TODO connectionsFWDry break requiredCompatible FW / FO TODO connectionsConfirm receiving interfaces; complete before on-hire.

Bunkering concerns

FOS Gemini · pump capacity and stern manifold

3 · Cargo pump

Management has committed to fitting a higher-capacity pump during dry dock.

Feasibility is under review. The final transfer rate is not yet confirmed.

Check the whole bunkering transfer pathThe reported 40–50 kL/h ship-to-ship flow is not a guaranteed platform flow. Four bar is reported receiving pressure, not pump discharge pressure. The higher-capacity pump remains subject to piping feasibility and Class review and approval; final rate is unconfirmed.40–50 kL/hReported STS · max 60Platform rate may be lowerCargo pumpVessel pipingHosePlatform4 barReceiving pressureReported; confirmUpgrade depends on the whole transfer path and Class approval

4 · Manifold position

An additional stern manifold is planned to reduce the need for close approach.

Hose reach and vessel positioning need agreement.

Proposed additional port-side stern manifoldExisting amidships manifold remains. An additional manifold is planned at the port side of the stern to reduce the need for a close platform approach. Positioning and hose reach still need agreement.

Planned dry-dock work

Preparing FOS Gemini for Chevron’s 2027 campaign.

Bunkering system

  • Dry-break couplings for fresh water and fuel oil
  • Higher-capacity cargo pump
  • Additional port-side stern manifold

FiFi and deck machinery

  • Activate FiFi
  • Refit towing and tugger winches

Tests, survey and repairs

  • Bollard-pull test
  • CAP survey
  • Shaft-tunnel repair

Pump upgrade subject to vessel and platform piping capacity, and Class review and approval.

FOS Gemini
Delivery commitment and next steps

If Chevron agrees to the proposal, we commit to delivering FOS Gemini as a safe, reliable vessel for the 2027 campaign.

Delivery and on-hire at Tok Bali: TBC. Confirm a programme that completes the agreed work, Class close-out and Chevron acceptance beforehand.

Duties, routes, demand, timings and backup cover.

Resolve the four findings and agree the bunkering risk assessment, duties and communications.

Reconcile the fuel comparison; confirm the delivery programme and commercial terms.

Before closing, confirm the responsible contacts, outstanding information and next review date.
