Maersk Supply Service (MSS) says it has moved its last offshore vessel out of layup as part of a sale of three more anchor-handling tug supply units.

The 14,888-hp Maersk Tracer, Maersk Transporter and Maersk Tracker (all built 2009) have gone for undisclosed prices.

The latter two, now the Delta Vanguard and Delta Titan, have gone to Delta Logistics in Trinidad, brokers said.

The Maersk Tracer, which was laid up until December, has been acquired by Middle East buyers.

An MSS spokeswoman confirmed the sales and told TradeWinds: “We have no remaining vessels in layup.”

VesselsValue assesses the trio as worth about $33m, up from $15m two years ago, in buoyant offshore markets.

These are Delta Logistics’ first AHTS ships, but it has 10 platform supply vessels and two utility vessels.

Norwegian broker SSY Offshore now lists no PSVs laid up in North Sea ports, and just three AHTS units, down from more than 100 in the long slump that ended in 2021.

Rates for rig moves are currently NOK 450,000 ($43,400) per day.

Last July, MSS sold off two laid-up AHTS vessels, the 13,872-bhp Maersk Tackler and Maersk Trimmer (both built 2009), stacked in Fredericia, Denmark, since 2016.

All-time highs seen in 2023

VesselsValue assessed the pair as worth $19.2m combined.

AHTS rates hit an all-time record of $233,000 per day in the North Sea in June.

The sales marked a further reduction in the lay-up count for MSS.

In May, the owner sent three elderly offshore ships for green recycling.

The company, part of AP Moller-Maersk, said the trio was scrapped at Fornaes Ship Recycling in Grenaa, eastern Denmark.
