Case Study Overview
ABLE Seaton Port is located in the centre of the UK on the North East Coast close to the mouth of the River Tees and covers 51 hectares (126 acres) including a 10 hectare (25 acre) dry dock (currently wet) – one of the world’s largest. It is capable of handling all types of offshore construction vessels, has significant crane capacity and quays, which have been constructed particularly to suit the requirements of the heavy fabrication industry.
At a glance
- Location: ABLE Seaton Port, River Tees
- Plant used: 400T Haven SeaSeven
- What we did: Southbay Civil Engineering Limited together with its Marine Partner of Choice, Red7Marine completed the construction of two mooring dolphins on behalf of ABLE UK at its Seaton Port facility.
Southbay Civil Engineering was responsible for the construction of two new mooring dolphins, with the project commencing in October 2020. The mooring dolphins were constructed from Red7Marine’s 400t jack-up barge, the Haven Seaseven. Each dolphin consisted of 6no. 1420mm diameter tubular piles which were installed from a piling gate mounted to the side of the barge. The piling gate was fabricated in-house at Red7Marine’s quayside facility in the Port of Ipswich. Further works included the installation of precast units and FRC works to construct the deck. Each structure includes associated berthing facilities in the form of fenders, ladders, bollards and handrails.
The project was delivered throughout the winter months, facing challenging weather conditions and in accordance with a demanding programme to ensure minimal disruption to planned vessel movements. This involved progressing works across both day and night shifts. Significant pre-planning was required throughout the project to ensure materials were safely transported within a live operational environment. This involved transporting materials using a flat barge and supporting tug vessel.
Graham Taylor, Contracts Manager at Southbay Civil Engineering comments: “The site team maintained a collaborative working environment which allowed us to safely progress works in accordance with our clients ongoing operations. This in part was achieved by maintaining a proactive approach to planning all activities.”
Kristen Branford, Managing Director at Red7Marine comments: “As the UK’s Marine Partner of Choice, we pride ourselves on our ability to provide full-turn key marine packages to our clients. Our collaborative working relationship with Southbay Civil Engineering enhances the capabilities we can offer to the marine construction market and leads us to achieving a successful end goal.
Three of our Trainee Barge Masters have also been involved with the project since its inception, working day and night shifts rotationally and moving the barge to various locations to support the project and its timeline.”

In order to accommodate a new luxury apartment block in Brighton, part of the marina needed to be reclaimed using sheet piled cofferdams. This would enable the water to be kept out and foundations to be built for the stunning seafront properties. Red7Marine supported the installation of a sheet pile twin wall cofferdam.
Red7Marine installed replacement Active Effluent Discharge Lines at Oldbury power station as part of the on-going care and maintenance works. Red7Marine’s previous project experience on similar projects consisting of works on subsea pipeline and outfalls at Bradwell and Sizewell nuclear power stations, positioned the company as the ideal marine partner for client, Magnox.
Emirates Cable Car
The Emirates cable car was installed to provide a pedestrian link across the River Thames between the Royal Docks and the Greenwich peninsula. Red7Marine worked with Bachy Soletanche in a joint venture to install the foundations for the one-kilometre long cable car using marine rotary bored piling.
Battersea River Pier
Red7Marine secured a contract at Battersea in December 2016 to install new tubular driven steel mooring piles for the Battersea Power Station river bus pontoon installation which is planned to be operational in Autumn 2017. Transport for London (TFL) decided to extend the river bus service after the number of housing developments at Battersea began to increase.
Middleton Sands Navigation Marker
This fast turn-around marine construction project involved the installation of a new tubular steel navigation marker pile at Middleton Sands, Barrow-in-Furness in 2017. The navigation marker was required to identify the sub surface obstructions and enable other vessels in the area to operate safely.
Liverpool 2 Deep Water Port Extension
Red7Marine was the marine partner of choice for BAM Nuttall when they constructed a piled combi-wall as part of the Liverpool 2 Dock Expansion that began in 2014. The construction of the container terminal was supported by four of Red7Marine’s jack up barges; the Haven Seariser 1, Haven Seariser 2 and the Haven Seariser 3 and the Haven Seajack as it carried out rock socket piling works.
The Red7Marine team was chosen to provide specialist marine plant and personnel to aid the redevelopment of the Weston-super-Mare Grand Pier after it was destroyed in a fire in 2008. Red7Marine supplied the Haven Seajack 4 assisted in the pier construction works. Its previous experience in pier and marina construction works made it the ideal project partner for this development.
Bradwell Power Station Barrier Wall Removal
Red7Marine is a leading provider of equipment for marine demolition and is skilled in dismantling structures that are beyond the reach of ordinary demolition contractors. In 2012, Red7Marine removed approximately 800 tonnes of steel in the Blackwater Estuary from the Bradwell nuclear power station water intake structure.
Fingringhoe Firing Ranges
Red7Marine installed scour protection and provided remediation on damaged sections of the flood defences to preserve areas of the salt marsh at the Fingringhoe firing ranges in Essex. Scour protection and remediation techniques are used to control erosion in both estuarine and the offshore environments.
