Rolls-Royce and Sanmar Shipyards in Turkey have signed a contract for the delivery of eight Rolls-Royce MTU enginesto  power new Harbour tugs, including an option for a further four engines. The tugs will each be fitted with two 16V 4000 M73L MTU engines, each delivering an output of 2,700 kW (at 1,850 rpm). The MTU brand is part of Rolls-Royce Power Systems.

Ali Gürün, Projects Director of Sanmar Shipyards, commented: “We were impressed by MTU’s technical support, the service and the reliability of the MTU engines, which is why we will also be equipping our new Robert Allen/ Rastar 2900sx tugs with MTU engines.” Sanmar and MTU have been working closely together since 2009.

Early on 9 April 2016, the fishing vessel Louisa foundered, with the loss of three lives, while anchored close to the shore in Mingulay Bay in the Outer Hebrides.

The skipper and crew, who had been working long hours before anchoring late the previous evening, had woken suddenly as the vessel was sinking rapidly by the bow. They were able to escape to the aft deck, activate the emergency position indicating radio beacon (EPIRB), and to don lifejackets. However, they were unable to inflate the liferaft as they abandoned the vessel.

The US Coast Guard has confirmed that from 20 July 2017 a portion of Subchapter M is now fully operational for towing vessels with keels laid, or major conversions on or after July 20. These vessels are now required to meet 46 CFR Subchapter M and must obtain a Certificate of Inspection (COI) prior to operating.

Additionally, starting July 20, 2018, a portion of existing towing vessels will have one year to meet all of Subchapter M and obtain COIs. As discussed in Subchapter M, owners or managing operators of more than one existing towing vessel, required to have a COI, must ensure that each existing towing vessel under their ownership or control is issued a valid COI, according to the following schedule:

Summary of the incident
At 1135 on 15 May 2016, the passenger vessel Surprise suffered hull damage and started flooding when it grounded at Western Rocks, Isles of Scilly. All 48 passengers were safely evacuated to shore. The flooding was contained by the passenger vessel Surprise,  own bilge pumps and it returned to harbour under its own power.

Resulting safety issues
A passage plan had not been prepared for the trip. Passage planning is essential for every voyage to ensure all navigational hazards are identified and avoided.

BB Green, the world’s first fully electric air supported vessel by Green City Ferries has been awarded the ‘electric and hybrid propulsion system of the year’ at the Electric & Hybrid Marine World Expo Conference 2017 in the Netherlands.

The fourth annual Electric & Hybrid Marine Awards took place in Amsterdam where a judging panel made up of leading international marine journalists, industry experts and academics, honoured the world’s finest engineers and innovative products in the electric and hybrid marine arena. The BB Green is used as a commuter ferry for up to 99 passengers on the inland waterways around Stockholm.

Rolls-Royce and global towage operator Svitzer have successfully demonstrated the world’s first remotely operated commercial vessel in Copenhagen harbour, Denmark. The companies have also signed an agreement to continue their cooperation to test remote and autonomous operations for vessels, such as autonomous navigation, situational awareness, remote control centre and communication.

Earlier this year, one of Svitzer´s tugs, the 28m long Svitzer Hermod, safely conducted a number of remotely controlled manoeuvres, RR informed. From the quay side in Copenhagen harbour the vessel’s captain, stationed at the vessel’s remote base at Svitzer headquarters, berthed the vessel alongside the quay, undocked, turned 360°, and piloted it to the Svitzer HQ, before docking again.

VEKA Group set to build the world’s first hybrid trimaran for transporting personnel offshore

Workers on drilling rigs and offshore wind farms can hopefully look forward to a more pleasant commute to work with considerably lower risk of seasickness thanks to a special, innovative ship built by VEKA Group. VEKA will be building two trimarans intended specifically for transporting personnel and freight to offshore wind farms. These are the first hybrid trimarans in the world. Transporting offshore personnel takes place mainly by catamaran. These will be VEKA’s first trimarans.

Most of the innovations are intended to make the so-called workboat more stable and more comfortable, thereby reducing the risk of seasickness. For example, the ships have lower windows than is customary, so that the passengers have a better view. The third bow is designed to ensure additional stability and comfort. There are also innovative stabilisers built into the hull.

Wärtsilä has developed a new water lubricated seal, Enviroguard SLR, which provides cost-effective reliability for small workboats.

Available in nine standard sizes that suit 75mm-306mm of shaft size, the new seal is expected to provide more reliability to smaller workboats, fishing boats, motorised barges, and super yachts.

The Wärtsilä Enviroguard SLR water lubricated seal is also designed to survive large shaft movements and to tolerate aggressive waters that are heavy with silt or sand.

MAIB report into the grounding and capsize of berthed trawler Saint Christophe 1

MAIB report into the grounding and capsize of berthed trawler Saint Christophe 1

On 9 March 2016, three French fishing vessels sought shelter from bad weather in Dartmouth harbour, on the south-west coast of England. One of the vessels, Saint Christophe 1, was directed to berth alongside a quay wall and when the tide went out it grounded and capsized alongside. The berthed trawler Saint Christophe 1 subsequently flooded and sank with the incoming tide, and was declared a constructive total loss.

Safety issues
The lack of effective communication between harbour authority staff and vessel’s crew failed to ensure a common understanding of the fact that the boat would ground at low water
The assumption that the crew understood the information provided by the harbour staff, prevented further safety checks from being made

The MAIB has issued its report into the capsizing and sinking of the scallop dredger JMT in 2015. The report will be of particular interest to surveyors given that the incident raises issues around the effect modifications made potentially had on the stability of the craft.

During the afternoon of 9 July 2015, routine contact was lost with the skipper and crewman on board the 11.4m scallop dredger JMT that was fishing off Plymouth, UK. A search and rescue operation was initiated the following morning when the vessel did not return alongside as expected.

Beware signage dropping from a crane boom warns IMCA

Warning of Signage dropping
Warning of Signage dropping

In one of its regular safety bulletins, the International Marine Contractors Association (IMCA) has issued new information on an incident involving parts falling from a crane – in this instance a steel sign. IMCA says that this is not the first time this has happened and individuals may wish to review this in light of other similar reported signage dropping incidents.

A piece of metal fell from a crane boom. The incident occurred on a vessel whilst alongside during the testing of the luffing motors’ braking system on the main crane. During this testing the crane boom made an uncontrolled descent into its crutch, resulting in a 60 kg steel sign falling 15m down to the deck. Investigation revealed that the sign was fixed by 4 x stitch welds, of which three were completely rusted away.
