MacGREGOR supplies lashing equipment for 10 newbuildings + two options for Laeisz

The adoption of AFC-1 automatic fixing cones and CV-20 semi-automatic twistlocks provides a unique solution to the US Occupational Health & Safety Administration's (OHSA) legislation which aims to ban conventional container securing twistlocks from ports in the USA.

The latest vessels ordered by German shipowner Laeisz (charterers DSR/Senator & Choyang) are fitted with MacGREGOR container lashing equipment complying with the latest US safety requirements.

The ten confirmed orders (newbuilding Nos 1004-1010 and 1022-1024) have been placed with the South Korean yard of Hyundai Heavy Industries Co, Ltd, at Ulsan. All are 4,545 TEU vessels with delivery covering a ten-month period from June 1997 to March 1998. The two options are for delivery in 1998. All are to be classed with Germanischer Lloyd and will have a length overall of 294.13m on a beam of 32.20m. The hull length between perpendiculars will be 283.20m and the moulded depth 21.80m.

On the weather deck MacGREGOR's comprehensive container lashing and securing package includes CV-20/DUAL/2 twistlocks, AFC-1 automatic fixing cones, and the famous TSB-3G/1 and LB-11 multilash systems. The 20ft containers within cellguides in holds will be connected with double stacking cones at midhold, and the transversal forces are transmitted into the hull structure by use of tension/pressure elements. Underneath the hatch cover panels there are three independent container blocks with pressure elements in between which can be loaded/unloaded separately. Alternatively, the 20ft containers can be stowed up to 4 tiers on the tank top using only single stacking cones, but they have to be topped by at least one 40ft unit.

Conventional twistlocks are specified to secure the lowermost container tier directly on the hatch covers and deck stanchions. In between the container layers the CV20/DUAL/2 twistlocks and the automatic fixing cones AFC-1 will be used. The adoption of AFC-1 automatic fixing cones and CV-20 semi-automatic twistlocks provides a unique solution to the US Occupational Health & Safety Administration's (OHSA) legislation which aims to ban conventional container securing twistlocks from ports in the USA. The OHSA regulation sets out to improve stevedore safety by preventing stevedores and other employees from climbing onto the top of the containers on ships for cargo and container operations in the USA.

Semi-automatic twistlocks alone may not solve the problem completely because such twistlocks can only be opened from above in the 76mm ISO-gap that is created when two 20ft containers are stored on a 40ft stack. MacGREGOR Securing Division's solution is the combination of semi-automatic twistlocks along with the company's newly developed Automatic Fixing Cone (AFC-1). Semi-automatic twistlocks such as the CV-20/DUAL/2 (or alternatively the CV-14) solve the general application problem, and the new AFC-1 solves the special problems in the 76mm ISO-gap.

Using AFC-1s at the ISO-gap ends of 20ft containers and semi-automatic twistlocks at the outer ends ensures that the 20ft containers are secured in place when the twistlocks are locked. In addition to the added safety factor and compliance with the proposed new requirements, the use of AFC-1s also offers considerable time-saving advantages during cargo loading and discharge operations.

All the equipment is to be supplied by MacGREGOR's Securing Division, based in the German city of Bremen. The company name of MacGREGOR-Conver is being changed to MacGREGOR (DEU) GmbH under a corporate restructuring policy within the MacGREGOR Group. For an interim three-year period the product brand name will continue to be marketed as MacGREGOR-Conver. Thereafter, the product will adopt the MacGREGOR name alone in-line with the Group's "one name/one logo/one brand" strategy.
