The Epic Madeira and Tempest carrying out an STS operation in Portland Harbour

STS Marine Solutions Commission Portland as an STS location

The Portland Port group, in direct cooperation with leading energy transfer specialist STS Marine Solutions Ltd, has commissioned the port’s first STS operation.

The LPG STS transfer took place in Portland Harbour on April 29 at an inner anchorage to reduce the exposure to potential stronger elements at the outer anchorage. The operation demonstrated the port and STS Marine Solutions’ ability to handle small sized vessels, ensuring a safe and efficient turnaround for the customer.

STS transfers of LPG product can also take place at an outer anchorage or alongside at Portland Port.

STS Marine Solutions is a world-leading ship to ship service provider with more than 36 years’ experience in crude oil, refined petroleum, LPG and LNG transfers. 

Ian McQuade, General Manager Commercial, commented that “the port’s first STS operation, carried out in conjunction with STS Marine Solutions, was a huge success for everyone involved.  This first operation showed just how well the port and STS Marine Solutions work with each other, and we look forward to carrying out many more STS operations together.  Portland Port is ideally located, we have deep water with sheltered anchorages and berths, all of which is in close proximity to the main English Channel shipping lanes.”

Ian Laws, CEO of STS Marine solutions said: “This is a true milestone for the port and one we are very proud to be instrumental in.  This is why the ship-to-ship industry selects STS Marine Solutions as their first-choice service provide, it’s our ability to deliver on proof of concept”

As the Statutory Harbour body, Portland Harbour Authority is required to ensure that all STS operations take place safely and all the necessary risk assessments are carried out in conjunction with STS Marine Solutions.

Previously a naval dockyard for over 150 years, Portland Harbour is now a thriving and successful commercial facility. It still maintains a close relationship with the past through its ongoing contract to support the RFA, as well as being home to the activities of Global Marine and Portland Bunkers UK. It has almost 2,500 hectares of water at depths of up to 15m (C.D.); and provides vessel services from long term lay-ups to brief maintenance calls, luxury cruise liner docking facilities to industrial cargo shipments.

Portland Port has over 2,000 metres of alongside berths and 11.6 metres (C.D.) depth of water at the deepest alongside berth. 

Berthing for vessels up to 350 metres (subject to Harbour Master’s discretion). 

11 designated anchorages are within the 1,015-hectare inner harbour.  Six designated anchorages are within the 1,436-hectare Outer Harbour. 

A width of 210 metres and depth of over 12.6 metres (C.D.) at the entrance of the harbour mean that there are few vessel beam, lock, or air draft restrictions.
