The securing of containers on deck on a container ship

Container shipThere are six different ways in which ships move in the sea, primarily pitching, heaving and rolling.

Lateral rolling motion represents the greatest challenge for stacks of containers. If containers are to be transported safely on the deck of a container vessel, they must be firmly connected to the ship. This is done with the aid of what are known as twistlocks. These twistlocks are inserted into the corner castings of the containers. These corner castings have elongated holes in which the rotating lug of the twistlock engages, locking the containerstogether. In addition, the bottom two layers of the stacked containers are connected to the ship with lashing rods. Initially, it was common practice to stow stacks of containers on deck in such a way that the individual stacks were connected to each other Continue reading “The securing of containers on deck on a container ship”

The Human Side

When the Titanic sank in 1912, many crewmembers went down with the ship so that passengers could survive. When the cruise ship Oceanos foundered off the coast of South Africa in August of 1991, most of the crew – including the Master – abandoned the vessel, leaving the passengers to fend for themselves. In 2012, after running his ship onto the rocks, Captain Francesco Schettino of the Costa Concordia gained infamy and imprisonment when he claimed he fell into a lifeboat and lost consciousness, leaving his passengers and most of his crew behind.

The Expected Life Span of Yacht Enclosures

What is the expected life span of an enclosure? There are a lot of variances, and this article is prepared to give you the information needed to determine the life of a given enclosure.

Soft Enclosures

The least expensive of boats will typically have roll vinyl curtains. These are made from a clear pvc material that typically comes 51” wide on a roll and can be .015, .020 or .030 in thickness. It is soft and the life span is very short and unremarkable.

Better boats may have pressed polished sheets. These are made using the roll vinyl Continue reading “The Expected Life Span of Yacht Enclosures”

Hidden benefits of a shipboard asbestos survey

Shipboard asbestos survey
Shipboard asbestos survey

Inventory of Hazardous Materials (IHM) surveys, when carried out correctly, can have a range of unexpected benefits for ship owners. A recent experience not only highlights the value to ship owners of having an approved inventory for their vessels, but also reaffirms the need to ensure that surveys are undertaken correctly.

Hazardous materials consultancy Lucion Marine was appointed to assist a major cruise line with work on a 2008-built cruise vessel. In this particular case a shipyard, on a pre-refit visit, claimed that an area where a new scrubber installation was planned contained asbestos in the bulkhead fire insulation.

The role of the marine surveyor – a P&I club’s perspective

…The ship wherein Theseus {ref.2} and the youth of Athens returned had 30 oars, and was preserved by the Athenians down even to the time of Demetrius Phalereus for they took away the old planks as they decayed, putting in new and stronger timber in their place…

per Plutarch in Life of Theseus {ref.3}

Like their predecessors of ancient times, the marine surveyors of today inspect and make recommendations in respect of the state of seaworthiness (or lack thereof) of a vessel. Unlike their predecessors, and unsurprisingly, their role has expanded. Continue reading “The role of the marine surveyor – a P&I club’s perspective”

MCA releases the outcome of the review of the standards relating to older domestic passenger vessels

MCA release results of second public consultation
MCA release results of second public consultation

The Maritime and Coastguard Agency (MCA) carried out a second public consultation, which ran from 29 May 2019 to 10 July 2019, on proposals resulting from a review of the standards relating to older domestic passenger vessels, which are currently less stringent in some areas than those which are applied to newbuild vessels. Some proposals had been revised in the light of comments received during the first consultation, which ran from 6 November 2018 to 29 January 2019.

In some cases, there is a safety gap between the standards for new ships and those for older vessels. The review seeks to bring the standards applied to existing vessels into line, wherever possible, with those which apply to new vessels in key safetyareas.

These proposals are to narrow the gap by means of new Regulations which amend Continue reading “MCA releases the outcome of the review of the standards relating to older domestic passenger vessels”

CTV shortage as offshore wind growth accelerates warns naval architect

CTV shortage

A naval architect has warned that as European offshore wind markets continue to expand with larger and more ambitious projects, there is a looming shortage of Crew Transfer Vessels (CTV).

Chartwell Marine said that expedient investment in new builds will be required to tackle a shortage of 22m – 24m offshore wind crew transfer vessels, especially as build slots at yards are limited. Many of these existing vessels, commonly used for UK CTV operations, have reached retirement or require a refit following over 10 Continue reading “CTV shortage as offshore wind growth accelerates warns naval architect”

At 0930 on 7 December 2017, the skippered charter yacht Tyger of London departed San Sebastian, La Gomera, bound for Marina San Miguel, Tenerife, with four paying passengers acting as crew on board.

At about 1700, 1 nautical mile south of Punta Rasca, the crew heard a loud bang. Tyger of London immediately heeled to starboard, capsized and inverted. The crew released their lifelines, fell from the cockpit into the water and their lifejackets automatically inflated. One crew member was briefly trapped below the yacht but managed to swim clear.

The skipper of another yacht, St Barbara V, which was 200m to the west, raised the alarm and rescued the crew from the water. Once landed in Tenerife, they were treated by Spanish emergency services before being released. There were no serious injuries. Continue reading “Keel failure and capsize of charter yacht Tyger of London MAIB report published”

Safe Return to Port: Surveyor expertise produces guidance

REG publish guidance Safe Return to Port

Guidance to help surveyors interpret rules governing Safe Return to Port has been published by the Red Ensign Group. It follows work done by individual members of the REG and its Technical Forum which has now signed off the guidance for publication.

Safe Return to Port requires passenger vessels which are 120 metres or longer or with three or more main vertical zones to be designed for improved survivability. The rules are designed to make sure cruise ships and large yachts can get back to Continue reading “Safe Return to Port: Surveyor expertise produces guidance”

Corrosion nightmare in tanks, and how to mitigate

Corrosion is a concern for tank container owners and operators
Corrosion is a concern for tank container owners and operators

Corrosion is a perennial concern for tank container owners and operators. The stainless steel construction is resistant to staining and corrosion, but may be vulnerable to pitting from certain cargoes or certain cleaning and maintenance operations. Visually minor pitting may conceal development of substantial or even catastrophic corrosion below the surface.

It may be expected that UN Class 8 dangerous cargoes (Corrosive Substances) are the predominant challenge where corrosion of UN portable tanks (tank containers) is concerned, although such commodities are not alone in presenting risk. In terms Continue reading “Corrosion nightmare in tanks, and how to mitigate”
