Modern slow speed, two stroke diesel engines often have locating pins or pegs to keep the piston rings in a fixed position. Why is this arrangement used?

It ensures the rings cannot be mixed up and that they are fitted in the correct order on the piston.

It avoids the risk of the ends of the piston rings being forced out by the gas pressure and catching on the scavenge ports.

The piston ring gaps can be kept in line to control the gas pressure on each of the rings.

The piston rings are more difficult to lubricate because of the slow operating speeds and will wear more quickly if they are allowed to rotate.

In discussing segregation, the IMDG Code defines what it means by the term "separated from". Which of the following is that definition?

Either in a vertical or horizontal separation: if the intervening decks are not resistant to fire and liquid, then only in a longitudinal separation is acceptable. For "on deck" stowage, this means a distance of at least 12 metres. This distance also applies to one package stowed "on deck" and another in an upper compartment.

With an intervening compartment, being both a vertical and horizontal separation. Provided an intervening deck is resistant to liquid and fire, a vertical separation of 6 metres is acceptable. For "on deck" stowage, this segregation means a distance of at least 12 metres irrespective of compartment divisions.

Effectively segregated so that the incompatible goods cannot interact dangerously in the event of an accident, but may be transported in the same compartment or hold or on deck, provided a horizontal separation, projected vertically, of 3 metres is obtained.

In different compartments or holds when stowed "under deck". Provided an intervening deck is resistent to fire and liquid, a vertical separation may be accepted as equivalent. For "on deck" stowage, this segregation means a distance of at least 6 metres.
