Agreed Safety Percentage

Jan 29 2015

During our daily load-outs, we meet many different parties; shipping lines, supercargoes, surveyors, clients and insurance companies.

Having an opinion is very good, because communication should always be open and in the end and opinions should lead to results. A result of how the load-out should occur, under which restrictions, rules and...

Friction included or excluded in calculations?

Oct 02 2014

Friction is a magic word in transport engineering. For some companies it means saving money on lashing & securing. For another companies it means to create additional safety for the cargo. When is friction used? How is it used? We all know what the coefficient of friction will be when using steel on timber, or steel on steel etc. Some rubber mats manufacturers state they have mats which could create a coefficient of 0,8g. Amazing…No more lashing and securing for shear...

Safety Factor

Using safety factors is getting out of hand. Companies use it to increase their safety in load-outs, or is it because they are not sure of themselves? When cargo is loaded onto a vessel according IMO Annex 13, acceleration factors will be taken from a table or calculated by using formulas. The achieved acceleration is always very high. This is done to have a single guideline for all sort of vessels. However, if you engineer the acceleration forces they are...
