M - This symbol signifies that the anchor, chains or wire rope, which have been specified by the
Owner for position mooring, have been tested in accordance with the specifications of the Owner and
in the presence of a Surveyor. It is applicable to ship type displacement hull designed for offshore
operation as well as to multiple hull design. The symbol M is placed after the classification notation.
Circle E, is a ABS classification symbol that signifies that the equipment of anchors and chain cables of the vessel is in compliance with the requirements of the Rules.
I assume that the "diameter of a triangle" means the diameter of the smallest circle containing it. Assume the triangle has sides a, b and c and angles A, B and C (where angle A is opposite side a etc.). Calculate angle A from the law of cosines. Then: a^2 = b^2 +c^2 - 2*b*c*cos(A) so: A = arccos((b^2 + c^2 - a^2)/(2*b*c)) -------------------(1) Then, using the usual construction for finding the center, O, of the circumscribed circle (i.e. a perpendicular bisectors of each side is constructed and all three meet at point O) we can draw the radius from O to A. This will divide angle A into two smaller angles (in some cases one angle will be larger than A and the other will be negative, but they will still add up to angle A). Using simple trigonometric formulas we can calculate angle A by adding the two together. The result then is: A = arccos(b/(2*r)) + arccos(c/(2*r)) -----------------------------(2) If we then equate the right hand sides of (1) and (2) we get an equation involving a, b, c and r. These can be solved to find r in terms of a,b and c. I used the easy way using Maple and got the result shown below. r = abs[sqr(-b^4+2*b^2*c^2+2*b^2*a^2-c^4+2*c^2*a^2-a^4)*a*c*b]/ [ b^4-2*b^2*c^2-2*b^2*a^2+c^4-2*c^2*a^2+a^4] The diameter is, of course, 2*r. This answer checks the cases for an equilateral triangle and for a 3,4,5 right triangle, each of which is easy to do by much simpler methods.
Circle E, is a ABS classification symbol that signifies that the equipment of anchors and chain cables of the vessel is in compliance with the requirements of the Rules.
ABS stands for Amateur Butt Slapping.

Tailshaft Condition Monitoring (TCM) - This notation is assigned to vessels with tailshafts specifically arranged with oil-lubricated stern tube bearings, complying with the requirements of the ABS Guide for Classification Notation Tailshaft Condition Monitoring (TCM).
This non-mandatory notation is assigned to indicate that drilling systems and equipment comply with the ABS Guide for the Certification of Drilling Systems. The symbol À will be omitted if the drilling systems and equipment, although complying with the Guide, have not been manufactured and installed under survey to ABS.
AMS is a classification notation that, together with the Maltese Cross + symbol, indicates that a vessel's machinery, boilers and systems have been constructed and installed under survey by the American Bureau of Shipping (ABS) in accordance with the requirements of the ABS Rules. The + AMS notation is intended for all new construction of ABS classed self-propelled vessels and offshore units. The AMS notation, without the Maltese Cross + symbol, is assigned to self-propelled vessels and offshore units for which the machinery, boilers and systems have not been constructed and installed under survey by the Bureau, but are found satisfactory with regard to ABS requirements.
SafeHull Construction Monitoring (SHCM) - This notation is assigned to vessels that have been found in compliance with Part 5C, Appendix 1, "Guide for SafeHull Construction Monitoring Program" of the ABS Rules for Building and Classing Steel Vessels. This notation is required for Oil or Fuel Oil Carriers, Bulk or Ore Carriers, Combination Carriers and Container Carriers designed to Part 5C, Chapters 1, 3 and 5 of ABS Rules for Building and Classing Steel Vessels, respectively. The SHCM notation is also required for Membrane Tank LNG Carriers that have been designed in accordance with the ABS Guide for Building and Classing Membrane Tank LNG Vessels and assigned the SafeHull notation SH and for Liquefied Petroleum Gas Carriers with Type-A Independent Tanks that have been design in accordance with the ABS Guide for Building and Classing Liquefied Petroleum Gas Carriers with Type-A Independent Tanks and assigned the SafeHull notation SH.

ACCU indicates that a self-propelled vessel is fitted with various degrees of automation and with remote monitoring and control systems to enable the propulsion machinery space to be periodically unattended and the propulsion control to be effected primarily from the navigation bridge. Where periodically unattended propulsion machinery space is intended, the provisions of class rules (Example ABS Rules for steel vessels, Part 4, Section 4-9-4 ) are to be complied with. Upon verification of compliance, ACCU will be assigned.
ABS is a type of plastic
