Repairs main hinge pins and bearings, Cammell Laird reinstalled the bow visor and carried out a series of inspections and water tests to ensure that seal integrity had not been compromised. Cammell Laird has recently secured a new four-year contract for the annual maintenance and dry docking of CalMac’s five largest vessels, which provide an essential service between the Inner and Outer Hebrides and the Scottish Mainland. All five ferries will dock annually at Cammell Laird, with the first vessels arriving in early 2021.

Work on the bow visor of the Isle of Mull at Cammell Laird

Drydockings in Atlantic & Peninsula Marine Services Atlantic & Peninsular Marine Services operates two repair companies in the UK – A&P Group and Cammell Laird. A total of 42 extraordinary drydockings and unscheduled repairs contributed to A&P Group’s strong performance in 2020 - despite the challenges of operating during a pandemic. Boskalis’ 8,234 gt offshore construction/ diving support vessel Rever Polaris, renamed Boka Polaris, visited A&P Tyne in November for hull repairs and upgrades. Plates were templated, profiled and rolled at A&P’s on-site fabrication facility and a number of smaller welds were also carried out. New structural members were also profiled and fitted to the tanks to provide additional stiffening. While the vessel was in the drydock, other works included a full repaint of the hull, sea chests and vertical sides; replacement of the umbilical supports in the dive bell; manufacture of new hot water pipes and removal of the external stairs for steel repairs. Prysmian’s 9,778 gt offshore supply ship Normand Pacific also visited A&P Tyne in 2020 for a complex blend of fabrication, mobilisation and marine work. Due to a tight schedule, A&P began the manufacture of the new 54 tonne mezzanine structure, stairs and grillages on-site 28 days prior to the vessel’s arrival. Mobilisation involved multiple contractors on site and stringent consideration of COVID-19 guidance. A number of significant lifts were involved in order to ready the mezzanine for the addition of deck grating, handrails and cable

trays, and its subsequent installation on the vessel. The team also assisted with the installation of the azipod thruster and a new 120 tonne A Frame lifting system for the vessel’s Searex ROV. The A Frame lift involved all three of A&P Tyne’s dockside cranes and took a full day to complete. Once complete, hydraulic and electrical work was undertaken and more than 300 hydraulic hoses on the offshore crane were replaced. At A&P Falmouth, the team delivered a comprehensive programme of major steel repairs for Kahrs Bereederung’s 9,313 dwt containership Samskip Express after she ran aground while sailing to Ireland. A 76 day stay at A&P Falmouth involved extensive repairs to the shell plating and several areas of the ship’s ballast pipework. A&P fabricated temporary support pillars to protect the structure of the vessel throughout the repairs and ensured that work on adjacent areas didn’t take place simultaneously. In total more than 60 tonnes of steel was replaced in seven different areas of the hull. Meanwhile, A nine day project to replace bow visor hinge pins and bearings for CalMac Ferries’ 4,719 gt ro/pax ferry Isle of Mull has been completed by UK’s Cammell Laird, Birkenhead. Delivered as part of the vessel’s annual survey, the project involved a multi-disciplinary approach from Cammell Laird’s planning, technical and lifting teams in order to remove the vessel’s 33 tonne bow visor and replace its hinge pins and bearings. The programme involved a series of heavy lifts using 200 tonne jacks and a 350 tonne mobile crane to transfer the bow visor to rigging on the bottom of Cammell Laird’s No 6 drydock. Following replacement of the bow visor’s

Busy times at Remontowa Nissen Kaiun’s 14,022 dwt reefer vessel Star Care is the second ship belonging to this Japanese shipowner to be drydocked at Poland’s Remontowa, Gdansk this year. Work on both vessels has included the installation of a scrubber system. This follows the successful repair of some four ships from Nissen Kaiun drydocked in 2019, work on these vessels also including the installation of BWM systems. Teekay Shipping’s 92,995 dwt shuttle tanker Petronordic returned to the yard for a CAP Survey of 12 cargo tanks (plus two slop tanks). The yard also repaired the bow loading system. In addition, it carried out an overhaul of engine room equipment, as well as pipe work and hull maintenance with painting work. During Petronordic’s stay in the yard, Teekay, whose logo has so far appeared on the tanker’s funnel, was rebranded to Altera reflecting the change in the ownership structure. In the first half of November, the repair of OSM Shipmanagement’s 20,209 gt car carrier Viking Constanza was completed, and in the same month her sistership City of Oslo called at Remontowa. OSM Shipmanagement manages these vessels for Norway’s Gram Car Carriers. The scope of repair works on City of Oslo was very similar to the work carried out on-board the Viking Constanza and included bow thruster
