Offshore Vessel Operators on Mumbai High: What the 2025 Record Shows

A 2025 record, so check what is still running

The names here come from ONGC tender results, company filings and news from 2025 and 2026. The source describes them as operators and vessel owners that hold charter awards with ONGC or related operators on Mumbai High and the Indian west coast.

The awards and charter parties quoted below are all from 2025. Some charters will have ended and others will have been renewed or replaced. Before you build a requisition on any of them, ask the vessel's operator whether the charter is still running and where the vessel is working now.

A charter award tells you who is contracted to put a vessel on the field. It does not tell you the port, the berth or the next call.

Vessel types in the awards and what each means for stores

The 2025 ONGC charter tender awards show a mix of tonnage. Treat the type as the first filter for a stores list.

• Anchor handling tug supply vessels: SMS Serenity (80 ton BP, PT Wintermar) and Hai Duong (150 ton BP, Haduco). Expect heavy deck work, so ropes, wires and lashing gear deserve a close look.
• Offshore supply vessel: UOL Tigerfish (Alphard Logistics Pvt Ltd). A supply boat shuttles to and from the field, so ask how long it stays out before it returns.
• Platform supply vessels: AM Phoenix, AM Precious, AM Pearl and AM Power (Alphard Logistics Pvt Ltd). Four vessels from one owner are not four identical lists, so confirm each one separately.

Each of these was awarded L1 in an ONGC charter tender in 2025. L1 is a stage in the award process. It is not a statement about the vessel's schedule today.

Charter parties show a different shape of work

SEAMEC Limited appears in two Bimco charter parties. One covers the vessel MV GOODMAN with HAL Offshore for Mumbai High on the NLM9 project, signed on 13 Oct 2025.

The other covers SEAMEC III for the ONGC West Coast oilfield, for saturation and air diving, as a 70 day charter with a window of Oct 15 to 25 2025.

A diving support vessel has a fixed charter length and a stated window. Its crew, safety and engine needs are not those of a platform supply vessel, so do not copy one vessel's list onto another.

Turning a charter record into a requisition

The public record gives vessel type, operator and charter terms. It gives no crew count, no stores consumption and no port rotation, so the numbers must come from the vessel itself.

For a superintendent, three answers matter most. First, where the vessel takes stores: a berth at Mumbai port, an anchorage or a supply base. Second, how many crew are on board, since provisions and cabin items scale with people. Third, how long until the next port call, because that sets the quantity for consumables.

Where a charter has a fixed length, as with the 70 day SEAMEC III charter, plan quantities against that period and its stated window. Where the charter is open, ask for the expected time offshore and order to the voyage rather than to the vessel class.

Before you send the requisition

• Confirm with the operator that the charter is still running.
• Note the vessel type: AHTS, platform supply, offshore supply or diving support.
• Record the charter length and window if the operator has shared them.
• State the delivery point: berth, anchorage or supply base.
• Give the crew count on board and the provisions period.
• List items against catalogue codes, line by line.

Plan the requisition and request a quote

Work through the checklist below before you send a requisition for any vessel on the field. It keeps the charter facts and the stores list in one place, which makes a quote easier to check line by line.

Read about offshores, browse deck stores and safety equipment, or send your list through request a quote.

A2Z Ship Stores serves the port of Mumbai, and its range covers provisions, bonded stores, deck and engine stores and nautical equipment for vessels at berth and anchorage.

FAQ

What does L1 mean in an ONGC charter tender?

In the public record, vessels such as SMS Serenity and Hai Duong were described as awarded L1 in an ONGC charter tender in 2025. L1 is the lowest bid position in the tender, so confirm the final charter status with the operator.

Are these charters still current?

The awards and charter parties in the record are from 2025, and the source describes the operators as holding current awards at the time it was compiled. Ask the vessel's operator whether a given charter is still running before you plan stores around it.

How do I time a requisition against a fixed charter window?

Take the SEAMEC III charter, described as a 70 day charter with a window of Oct 15 to 25 2025. A buyer would size consumables to the charter length and agree the delivery point and date inside the window, then confirm both with the operator.

Do different vessel types need different stores lists?

Yes. The record shows anchor handling tug supply vessels, an offshore supply vessel, platform supply vessels and a diving support charter. Their work differs, so build each list from the vessel itself rather than copying a sister ship's.
