Subsea7 agrees to sell six Seaway7 vessels to HEA Energy

By Priya Raman

Subsea7 has agreed to sell six Seaway7 heavy-transport vessels to HEA Energy, with completion expected in the first half of 2027 and regulatory approval required.

The deal covers a fleet transaction, not a single ship sale. It also forms part of the company’s Saipem merger plan. One caveat remains. Closing still depends on regulatory approvals.

Takeaway: HEA Energy will acquire six ships, but the first-half 2027 closing is not yet certain.

What exactly is changing hands?

The transaction covers six open-deck semi-submersible heavy-transport vessels, whose cargo decks and partial submergence support controlled transfers of oversized marine cargoes from ship to shore.

Five of the vessels are owned by Subsea7 through Seaway7. One is chartered from a third party. The fleet comprises:

• Seaway Albatross
• Seaway Eagle
• Seaway Falcon
• Seaway Hawk
• Seaway Osprey
• Seaway Swan

That mix leaves one operational question open. The announcement does not explain how the third-party charter transfers. It also gives no crew, age, capacity, route or utilization data. Those omissions matter when judging fleet value.

Takeaway: The buyer gets a six-vessel group with mixed ownership, not six wholly owned ships.

Why does the Saipem merger matter?

The sale serves as the permitted business sale named in Subsea7's merger agreement with Saipem, linking the fleet disposal to a combination that remains proposed.

The sale therefore has two linked functions. It identifies the heavy-transport unit as a permitted disposal under the merger agreement. The release does not set a Saipem completion date. It does not explain the merger's other financial terms. Nor does it say whether the fleet sale is a condition of the merger.

Takeaway: The fleet sale supports the proposed merger structure, but the release gives no closing date for that merger.

What are the price and timing terms?

Subsea7 said the commercial terms, including cash consideration, "would remain confidential." Accordingly, the announcement discloses no sale price. It offers no financing detail or valuation benchmark. That leaves HEA Energy's purchase economics unverified.

Subsea7 expects completion in the first half of 2027, although regulatory approvals and other closing conditions could still shift that timetable under the announced conditions.

The target is a company expectation, not a guaranteed closing date. Applicable regulatory approvals form one stated closing condition. The release does not identify the approving authorities or submission dates.

Takeaway: Price and schedule are both provisional: the price is hidden, and approvals remain outstanding.

How does the dividend work?

The sale triggers a special dividend of 105 million, approved at an extraordinary general meeting on September 25, 2025, before final completion of the transaction.

The announcement renders the amount as "$ €105 million," using both dollar and euro symbols. That inconsistent notation does not establish which currency applies. The currency therefore remains unconfirmed.

The payment date is the earlier of two events. Those events are transaction completion and the day immediately before the proposed Saipem merger's effective date. Subsea7 said processing and distributing the funds "could take up to two weeks." The estimate concerns processing and distribution, not the approval timetable. If completion slips, the payment mechanics require the merger timetable as well.

Takeaway: The dividend amount is disclosed, but its currency and final payment timing remain conditional.

What should readers watch?

The watch point is whether regulators clear the sale on schedule and whether the H1 2027 closing holds, since undisclosed economics prevent any margin assessment.

Three milestones matter: regulatory clearance, the H1 2027 closing and the proposed merger's effective date. The dividend payment follows whichever comes first, subject to the stated processing period. Until closing occurs, neither value nor margin can be tested from public terms. Future updates on charter treatment or approval status could clarify execution, but the company has not promised price disclosure.

Takeaway: Watch the approvals and closing date; the missing cash terms leave the deal's margin open.
